Coolant specification
The cooling system is filled at the factory with a mixture of specially prepared water and at least 40%G 12 evo
coolant additive (TL-VW 774 L).
The proportion of coolant additive mustalways be at least 40% to protect the cooling system. If greater frost
protection is required in very cold climates, the proportion of anti-freeze additive can be increased. However, the
percentage of coolant additive should not exceed 55 %, as this would reduce the frost protection and the cooling
effect.
The coolant additive is dyed purple. The mixture of water and coolant additive provides anti-freeze protection down
to -25°C (-13°F), protects the alloy parts in the engine cooling system against corrosion, prevents limescale deposits
and significantly increases the boiling point of the coolant.
When refilling the coolant, a mixture ofdistilled water and at least 40%G 12 evo coolant additive must be used in
order to obtain the optimum corrosion protection →
.
WARNING
Insufficient anti-freeze in the coolant system can cause the engine to break down and cause serious injuries.
● The amount of correct coolant additive used must be sufficient for the lowest ambient temperature that you
expect the vehicle to be exposed to.
● Coolant can freeze at extremely cold outside temperatures, causing the vehicle to break down. Vehicle occupants
with inadequate winter clothing could then freeze to death as the heating will also no longer function.
NOTICE
If the liquid in the coolant expansion tank is not purple, the correct coolant has been mixed with another, unsuitable
coolant additive. Failure to observe this warning can result in serious malfunctions or damage to the engine and
cooling system.
● In such cases, have the coolant changed without delay.
● Never mix Genuine coolant additives with other coolants that have not been approved by Volkswagen
Commercial Vehicles.
Coolant and coolant additives can pollute the environment. Spilt service fluids must be collected then
disposed of properly and in an environmentally responsible way.
